THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 656,145, dated August14, 1900.

Application filed January 8, 1900. Serial No. 7&9. (No model) To aZZwhom it may concern.-

Beit known that I, JAMES CLARK PERRY, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Thin-Couplings, ofwhich the following is a specification.

My invention relates to thill-couplings, and its object is to provide asimple and inexpensive device of this character which will effectuallyprevent rattling of the parts and constitute a secure fastening for thethills.

The present invention is designed as an improvement upon theconstruction disclosed in United States Letters Patent No. 620,721,granted to me under date of March '7, 1899, and it is distinguished fromthe patented device by the employmentof a spring and fastening meanstherefor of novel construction.

The invention is embodied in the construction shown in the accompanyingdrawings, in which- Figure 1 is a vertical sectional view of theimproved coupling. Fig. 2 is a side elevation of the thill-iron andantirattler-spring detached from the shackle, and Fig. 3 isa top plan ofFig. 2.

The reference-numeral 1 designates a clip, of inverted- U shape,provided with forwardlyextending parallel ears 2, connected by across-bar 4, said ears and cross-bar constituting the shackle of thecoupling. The inner sides of the ears 2 are each formed with ahorizontal groove 5, communicating with a vertical groove 6. The grooves5 constitute bearings for the journals 7 projecting from opposite sidesof the thill-iron 8, and the vertical grooves 6 permit of the insertionof the thill-iron into the shackle, the journals pass ing through saidvertical grooves.

The upper side of the thill-iron is formed with lips 9 and 10, separatedby a slot 11 and adapted to overlap the upper end of aspring 12, whichis secured to the iron 8 by a screw 13. The spring 12 is curved to fitaround the rear end of the thill-iron, which consists of paralleloval-shaped ears 14, and the free lower end of said spring is held inposition against the under surface of the thill-iron by fingers 15,projecting rearward from theiron.

The front surface of the clip is recessed to receive a block 16, ofrubber, leather, or like yielding material, against which the curvedportion of the spring 12 bears.

It will be apparent that the contact of the spring with the rubber blockor buffer and the clamping of the ends of the spring by the lips 9 and10 and fingers 15 securely hold the parts against rattling movement, andat the same time the journals of the thill-iron are firmly seated in thebearings of the shackle.

I claim- In a thill-coupling, the combination with a shackle, formed onthe inner sides of itsside walls, with horizontal and vertical groovesof a thill-iron having projecting lips and fingers; a spring bent toembrace the end of the thill-iron, a screw securing one end of thespring, and a block of yielding material against which the spring bears.

In testimony whereof I affix my signature in presence of two witnesses.
